Bridge across the Morávka river at km 6.205
Hollý, Tomáš ; Marván, David (referee) ; Nečesal, Petr (advisor)
The subject of the thesis is to design and consider steel superstructure of a composite steel-concrete road bridge. It is a continuous beam with seven spans of 36,0 + 57,0 + 75,0 + 90,0 + 75,0 + 57,0 + 36,0 = 426 meters. The superstructure consists of welded I-beams, which pass into closed box girder. The calculations take into account the construction phase.

Bridge crossing over Svitava river and railway track in Blansko
Smělíková, Petra ; Konečný, Vojtěch (referee) ; Křižan, Lukáš (advisor)
The aim of the Diploma Thesis is elaboration of study of bridge crossing over the Svitava river and ČD railway track in Blansko. It concerns a five-pole steel beam road bridge with through-span which carries road of the third category. The static system of the construction is solved as solid-web beam of 1.3 meters height which is in three middle spans reinforced by truss construction with top chord and system of diagonals without verticals. The height of the main beam where reinforced by trusswork is 4.75 meters. The width of spans in the road axis is 18.5 + 30.525 + 44.4 + 30.525 + 18,5 metres. The bridge deck consists of steel cross beams bonded with reinforced concrete slab of 200 millimeters of thickness. The drive-through width of the roadway is 7.0 meters. The bridge is fitted with right-sided walkway placed on steel cantilevers. The walk-through width of the walkway is 3.0 meters. Material used is S355 Steel, C30/37 Concrete and S460 Steel which is used for marginal spans of the bridge. Load-bearing construction is assessed in compliance with current technical requirements laid down by European Directives, so called “Eurocodes”. The calculation of inner powers is performed using the Scia Engineer 2013.1 software.

Road bridge over the Budišovka river
Zývala, Pavel ; Požár, Michal (referee) ; Koláček, Jan (advisor)
The aim of this bachelor thesis is to design of bridge construction over the river of Budišovka located near the village of Budišov nad Budišovkou. The load bearing system is composed from one reinforced concretespan. The structural design was made in two variants, which were compared between them. For calculations of first way was used the software of Scia Engineering 16.1 and second way was calculated by simplified manual method of effective width. All calculations were performed according to actual standard EN.

Bridge on a motorway
Lindtner, Tomáš ; Řehulka, Martin (referee) ; Panáček, Josef (advisor)
The subject of Diploma’s thesis is the design of a road bridge on the R1 expressway, at km 1,293 above the road III/51311. The main content is static calculation of supporting structure consisting of four spans. Four studies were processed and the first variant of double-girder monolithic structure was chosen. The range of spans is ranging from 25 m - 30 m. Double-girder consists of two post-tensioned concrete beams and reinforced concrete slab. Static models and load effects are solved in Scia Engineer. Bridge is located in the horizontal curvature, however, compromise was elected (because of small curvature), assessing the upright design. Calculation is made without effects of temperature, wind loads and horizontal forces causing by traffic.

Road and tram bridge
Vošček, Martin ; Štrba, Michal (referee) ; Brosch, Petr (advisor)
The subject of this Diploma Thesis is to develop different alternatives of the road and tram bridge. It is a river bridge with the length of 52,5 m. There are compared two proposals, while in the first proposal it is an arch bridge with the tension bars. The second proposal which is also finalized as the winning proposal is the truss structure. Both proposals have composite deck. The structure is designed from steel S355 and concrete C35/45. The load bearing structure is designed in accordance with applicable technical standards.

Steel structure of the bridge on the road
Vlček, Radek ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The content of the thesis is a proposal of steel load-bearing structure (carrying structure of a steel) bridge of the span of 31+74+31m with the bottom bridge deck taking over the second-class road in the territory of Olomouc city. The bridge deck is created by composite steel-concrete slab with crossbars. The solution was focused on using arched construction in the middle of the bridge with different tilt of arches to the horizontal central axis of the bridge. Under the term of the solution four alternatives have been calculated. The most optimal solution was selected and processed in detail. The calculations were made in compliance with the Czech technical norms ČSN EN.

Design of a one-span bridge
Barič, Dominik ; Panáček, Josef (referee) ; Nečas, Radim (advisor)
The subject of this bachelor’s thesis is a design of a plate – girder bridge structure over the river „Svitava“, between the towns of „Blansko“ and „Brno“. The bridge carries a road of a class II, category S9,5/90. Three studies have been designed. Study A has been chosen for a detailed design. It has a character of post - tensioned plate - girder structure. Load analysis is performed in software Scia Engineer 17.1. The design and assessment are done by hand. Load caused by wind, snow and horizontal forces of traffic is passed by.

Bridge on a ramp
Otevřel, Rostislav ; Pachl, Radek (referee) ; Panáček, Josef (advisor)
Thesis describes the design and assessment of a plan view of a curved road bridge, which is a part of an elevated crossing transferring directional divided communication and tram line of public transport in Brno. There are four variants of cross sections designed, from which is selected bicameral cross section with arched angled bottom plate, which should be aesthetically pleasant to impress in an urban environment. Static calculation is processed and design is assessed by current European standards. Then clear and detailed drawings, the process of construction and visualization of the bridge are processed.

The bridge reconstruction
Schafferová, Denisa ; Svoboda, Adam (referee) ; Klusáček, Ladislav (advisor)
The aim of the bachelor thesis was to assess the load-bearing capacity of the existing load-bearing structure and to verify the effects of prestressing cables. Assessments were performed to comply with the ultimate limit state and serviceability limit state according to valid Europeans standards. Structural design was calculated by hand and partially checked with SCIA Engineer 20.0 software using ortothropic behavior for plates. The thesis includes detailed drawings of the existing structure.
